RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application, No. 61/854,738, “Methods and Graphical User Interfaces for Pointing and Editing on Computing Devices with Touch-Sensitive Displays,” filed by the applicant on Apr. 29, 2013.

TECHNICAL FIELD

The disclosed embodiments relate generally to mobile computing devices with touch-sensitive displays, particularly to computer-implemented methods and graphical user interfaces for enabling a user conveniently to point, select, and drag objects and edit content on a device with a touch-sensitive display.

BACKGROUND

Mobile computing devices with touch-sensitive displays such as smart phones and pad computing devices are two of the fastest growing categories of computing devices. These devices threaten to displace notebook and desktop computers as the preferred platform for many tasks that users engage in every day. Developers of these mobile devices have eschewed mouse and touchpad pointing devices in favor of on-screen graphical user interfaces and methods that have the user select content and edit content on touch-sensitive displays using direct manipulation of objects on the screen. Ording, et. al. describe one example of this current approach in US2010/0235770A1. However, the performance and usability of these current solutions is generally inferior to the mouse and/or touchpad based solutions commonly employed with conventional notebook and desktop devices. These current solutions do not support quick and precise pointing and selecting and dragging tasks for objects of all sizes. Whereas these current solutions support a simple task such quick selection of a single word or an entire content, they do not support quick selection of a particular item, object, character, group of characters, or group of words. In addition, they do not support equally well tasks performed at any location on the display ranging from tasks near the center of the display to those near the edge of the display. Whereas these solutions seek to support applications written for devices with touch sensitive displays, they do not support access to applications written for conventional notebooks and desktop devices designed for use with a mouse or touchpad. This effectively denies the user access to the host of applications that have been written for desktop and notebook computing devices. Furthermore, these existing solutions do not support “secondary click” actions and “mouse-over” actions commonly used in apps written for access by desktop and notebook computing devices. These existing solutions also do not support user setting of key control parameters to meet user preferences and user needs. Finally, these existing solutions do not support accessibility settings to enable the broadest set of users to access applications on these powerful devices.

We have developed methods and graphical user interfaces for pointing and selecting on computing devices with touch-sensitive displays that overcome the deficiencies of existing solutions.

The device detects the location of a finger gesture and type of finger gesture. Example finger gestures include, but are not limited to, a tap finger gesture (momentary contact of a single finger on the display with no motion across the display), a long-press finger gesture (extended contact of a single finger on the display with no motion across the display, with the duration of the finger contact being approximately 1 or 2 seconds for example), a two-finger-tap finger gesture (momentary and simultaneous contact of two fingers on the display with no motion across the display), a slide finger gesture (extended and uninterrupted contact of a single finger on the display together with motion across the display), and a tap-and-slide finger gesture (momentary contact of a single finger on the display with no motion across the display, followed by extended and uninterrupted contact of a single finger on the display together with motion across the display which begins at the location of the initial tap). The device responds to user gestures and displays a UI based upon the location and type of gesture that the device detects.

FIGS. 3A-3J, FIGS. 4A-4H, FIGS. 5A-5G, FIGS. 6A-6F, FIGS. 7A-7E, FIGS. 8A-8H, FIGS. 9A-9D, FIGS. 10A-10I, FIGS. 11A-11H, FIGS. 12A-12G, and FIGS. 13A-13E illustrate exemplary user interfaces for use in implementing the methods disclosed herein including but not limited to those methods presented in the flow diagrams in FIGS. 14-18. In each case we show a sequence of user interface (UI) drawings to illustrate the use of the UI to implement key elements of the methods.

FIGS. 3A-3J illustrate an exemplary user interface for positioning a pointer within read-only content on a handheld mobile computing device with a touch-sensitive display in accordance with some embodiments. FIGS. 3A-3D illustrate an example of displaying a pointer and changing the horizontal position of a pointer. FIGS. 3E-3F illustrate an example of changing the vertical position of a pointer. FIGS. 3G-3I illustrate an example of changing both the horizontal and vertical position of a pointer in one diagonal slide finger gesture. FIG. 3J illustrates examples of alternative embodiments of pointer positioning & control (PPC) icon 308 and pointer 310. In the figures, the pointer appears as the following symbol: I

The device displays read-only content 302 in UI 300A (FIG. 3A). The device may also display application navigation bar 304. A user may perform a long-press finger gesture 306 on the read-only content in UI 300A. In response to detecting the finger gesture on the content, the device displays UI 300B (FIG. 3B) with pointer positioning & control (PPC) icon 308 at a PPC icon first position and pointer 310 at a pointer first position. In one exemplary embodiment, the pointer first position is the location of the finger gesture on the content. In UI 300C (FIG. 3C), a user may perform a slide finger gesture 312 to 314 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from the pointer first position to a pointer second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 3C. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant. The device displays UI 300D (FIG. 3D) with pointer 310 at the second pointer position.

The device displays read-only content 302 in UI 300E (FIG. 3E). With the pointer at a first position, a user may perform a slide finger gesture 316 to 318 on PPC icon 308. In response to detecting ΔF_(y) (a change in the vertical position of an uninterrupted finger contact on the PPC icon), the device changes the vertical position of pointer 310 and PPC icon 308 such that ΔP_(y) (the change in the vertical position of pointer 310) and ΔPPC_(y) (the change in the vertical position of PPC icon 308) and are equal and proportional to ΔF_(y) as illustrated in FIG. 3E. This can be written as ΔP_(y)=ΔPPC_(y)=K_(y)ΔF_(y) where K_(y) is a proportionality constant. The device displays UI 300F (FIG. 3F) with pointer 310 at a second position. In this exemplary embodiment K_(y)=1.

A user may move both the horizontal and vertical position of pointer 310 with a single diagonal-slide finger gesture as illustrated in FIGS. 3G-3H. The device displays read-only content 302 in UI 300G (FIG. 3G). With pointer 310 at a first position, a user may perform a diagonal-slide finger gesture 320 to 322 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position) and ΔF_(y) (a change in the vertical position) of an uninterrupted finger contact on the PPC icon, the device changes the position of pointer 310 on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x), and such that ΔP_(y) (the change in the vertical position of pointer 310) and ΔPPC_(y) (the change in the vertical position of PPC icon 308) are equal and are proportional ΔF_(y), as illustrated in FIG. 3G. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant and ΔP_(y)=ΔPPC_(y)=K_(y)ΔF_(y) where K_(y) is a proportionality constant. Again, in this exemplary embodiment K_(y)=1. The device displays UI 300H (FIG. 3H) with pointer 310 at a second position.

A user may hide the pointer and PPC at any time. A user may perform tap finger gesture 324 at any location on the display screen that is not on the PPC icon. In response, the device displays UI 300I (FIG. 3I) in which both the pointer and PPC icon are no longer displayed.

In this description, we have shown one exemplary embodiment for a PPC icon for use in the exemplary UI. There are many different possible approaches to the design of the UI comprising a PPC icon 308 and a pointer 310. In reference to FIG. 3J we show several example embodiments. The PPC icon may be rectangular in shape with a horizontal extent substantially equal to the horizontal extent of the display in its viewing orientation. The PPC icon may be opaque and displayed at a position offset below the pointer as illustrated by PPC icon 308-1 and pointer 310-1. The PPC icon may be semitransparent and displayed at a position offset below the pointer as illustrated by PPC icon 308-2 and pointer 310-2. The PPC icon may be semitransparent and displayed at a positioned collinear to the pointer as illustrated by PPC icon 308-3 and pointer 310-3. The PPC icon may comprise a semitransparent frame around a clear central region displayed at a position collinear to the pointer as illustrated by PPC icon 308-4 and pointer 310-4. The PPC icon may comprise a semitransparent frame around a nearly transparent central region displayed at a position collinear to the pointer as illustrated by PPC icon 308-5 and pointer 310-5. The PPC icon may comprise a very narrow semitransparent rectangular region displayed at a position collinear to the pointer as illustrated by PPC icon 308-6 and pointer 310-6. In this last example, the exemplary PPC icon is the region that remains after removing one long side and the two short sides of the semitransparent frame PPC icon 308-5. There are other PPC icon designs that may be employed in user interfaces for use in implementing the methods of this disclosure.

FIGS. 4A-4H illustrate an exemplary user interface for positioning a pointer and selecting within read-only content on a handheld mobile computing device with a touch-sensitive display in accordance with some embodiments. The device displays read-only content 302 in UI 400A (FIG. 4A). The device may also display application navigation bar 304. A user may perform long-press finger gesture 306 on the read-only content in UI 400A (FIG. 4A). In response, the device displays UI 400B (FIG. 4B) with pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. In one exemplary embodiment, the pointer first position is the location of the finger gesture on the content. In another exemplary embodiment, the pointer first position is offset from the location of the finger gesture on the content. A user may perform tap-and-slide finger gesture 404 to 406 on PPC icon 308, as shown in FIG. 4C. In response, the device displays UI 400D (FIG. 4D) with selected text 408 displayed from a first position to a second position where the first position is located at the pointer first position and the second position is located at the pointer second position. The device may also display toolbar 410 with “Copy” icon 412. A user may perform tap finger gesture 414 on “Copy” icon 412 as shown in FIG. 4D. In response, the device displays UI 400E (FIG. 4E). Upon detection of tap finger gesture 416 on PPC icon 308 in UI 400E (FIG. 4E), the device displays UI 400F (FIG. 4F) with selected text 408 cancelled and no longer displayed and with pointer 310 positioned at the pointer second position. Upon detection of tap finger gesture 418 at a location not on PPC icon 308 on UI 400E (FIG. 4E), the device displays UI 400G (FIG. 4G), with text selection 408 cancelled and no longer displayed and with PPC icon 308 and pointer 310 no longer displayed. Upon detection of a page-scroll-up slide finger gesture 420 on content 302 on UI 400E (FIG. 4E), the device displays UI 400H (FIG. 4H) with both content 302 and selected text 408 scrolled up by an amount equal to the length of page-scroll-up slide finger gesture 420. Moving the content by page scrolling or other means does not move the pointer as illustrated in FIG. 4H.

FIGS. 5A-5I illustrate an exemplary user interface for positioning a pointer and a cursor within editable content on a handheld mobile computing device with a touch-sensitive display in accordance with some embodiments. In the figures, the cursor appears as the following symbol: I. The device displays editable content 502 in UI 500A (FIG. 5A). The device may also display application navigation bar 504. A user may perform tap finger gesture 506 on editable content 502 in UI 500A. In response, the device displays UI 500B (FIG. 5B) with cursor 508 at the location of tap finger gesture 506. In the case of devices having a soft keyboard in lieu of, or in addition to, a physical keyboard, the device may also display soft keyboard 510. A user may perform finger gesture 512 on the editable content in UI 500C (FIG. 5C). In one example embodiment, finger gesture 512 is a long-press finger gesture. In response to detecting the finger gesture on the content, the device displays UI 500D (FIG. 5D) with pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. In one exemplary embodiment, the pointer first position is the location of finger gesture 512. The device may also display toolbar 410 with “Paste” icon 516.

With pointer 310 at a first position, a user may perform a slide finger gesture 518 to 520 on PPC icon 308 as shown in UI 500E (FIG. 5E). In response to detecting ΔF_(x) (a change in the horizontal position) and ΔF_(y) (a change in the vertical position) of an uninterrupted finger contact on the PPC icon, the device changes the position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x), and such that ΔP_(y) (the change in the vertical position of pointer 310) and ΔPPC_(y) (the change in the vertical position of PPC icon 308) are equal and are proportional ΔF_(y) as illustrated in FIG. 5E. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant and ΔP_(y)=ΔPPC_(y)=K_(y)ΔF_(y) where K_(y) is a proportionality constant. Again, in this exemplary embodiment K_(y)=1. In this example, slide finger gesture 518 to 520 is a horizontal-slide finger gesture and ΔF_(y) is equal to zero (0). The device displays UI 500F (FIG. 5F) with pointer 310 at a second position. The positioning of the pointer on editable content is the same as that described above for positioning a pointer on read-only content. A user may perform tap finger gesture 522 at any location on PPC icon 308 as illustrated in FIG. 5F. In response, the device displays UI 500G (FIG. 5G) with cursor 508 at the position of pointer 310.

FIGS. 6A-6F illustrate an exemplary user interface for positioning a pointer and selecting within editable content on a handheld mobile computing device with a touch-sensitive display in accordance with some embodiments. The device displays UI 600A (FIG. 6A) with pointer positioning & control (PPC) icon 308 at a first position, pointer 310 at a first position, and cursor 508 at a first position. The device may also display toolbar 410 with “Paste” icon 516. A user may perform tap-and-slide finger gesture 602 to 604 on PPC icon 308, as shown in FIG. 6A. In response to detecting a tap finger gesture followed by ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 6A. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant. The device displays UI 600B (FIG. 6B) with selected text 606 displayed from the pointer first position to the pointer second position, and with pointer 310 displayed at the pointer second position. The device may also display toolbar 410 with “Cut” icon 612, “Copy” icon 412, and “Paste” icon 516. A user may tap “Copy” icon 412. In response”, the device displays UI 600C (FIG. 6C) with toolbar 410 no longer displayed. A user may perform tap finger gesture 616 on PPC icon 308 on UI 600C (FIG. 6C). In response, the device displays UI 600D (FIG. 6D) with the selected text 606 cancelled and no longer displayed and with the pointer 310 positioned at the second pointer position. A user may perform tap finger gesture 618 at a location not on PPC icon 308 on the content on UI 600C (FIG. 6C). In response, the device displays UI 600E (FIG. 6E), with cursor 508 displayed at the location of tap finger gesture 618, and with PPC icon 308 and pointer 310 no longer displayed.

FIGS. 7A-7E illustrate an exemplary user interface for precisely positioning a pointer horizontally within content on a handheld mobile computing device with a touch-sensitive display in accordance with some embodiments. FIGS. 7A-7C illustrate positioning a pointer the cases of K_(x)<1, K_(x)=1, and K_(x)>1. FIGS. 7D-7E, illustrate an example of positioning a pointer with two successive slide finger gestures. In the example shown in FIG. 7A, a user positions the pointer with K_(x)<1. The device displays UI 700A (FIG. 7A) with read-only content 302, pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. A user may perform horizontal-slide finger gesture 702 to 704 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 7A. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant and where K_(x)<1 for this example.

In the example shown in FIG. 7B, a user positions the pointer with K_(x)˜1. The device displays UI 700B (FIG. 7B) with read-only content 302, pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. A user may perform horizontal-slide finger gesture 706 to 708 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 7B. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant and where K_(x)˜1 for this example.

In the example shown in FIG. 7C, a user positions the pointer with K_(x)>1. The device displays UI 700C (FIG. 7C) with read-only content 302, pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. A user may perform horizontal-slide finger gesture 710 to 712 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 7C. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant and where K_(x)>1 for this example.

In the example shown in FIGS. 7D-7E, a user positions the pointer using two successive slide finger gestures on the PPC. The device displays UI 700D (FIG. 7D) with read-only content 302, pointer positioning & control (PPC) icon 308 at a first position and pointer 310 at a first position. A user may perform horizontal-slide finger gesture 714 to 716 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 7D. This can be written as ΔP_(x)=K_(x)→F_(x) where K_(x) is a proportionality constant. The device displays UI 700E (FIG. 7E) with pointer 310 at a second position. A user may perform a second horizontal-slide finger gesture 718 to 720 on PPC icon 308. In response to detecting ΔF_(x) (a change in the horizontal position of an uninterrupted finger contact on the PPC icon), the device changes the horizontal position of the pointer on the display from a first position to a second position such that ΔP_(x) (the change in the horizontal position of pointer 310) is proportional to ΔF_(x) as illustrated in FIG. 7E. This can be written as ΔP_(x)=K_(x)ΔF_(x) where K_(x) is a proportionality constant.

In one exemplary embodiment, the value of proportionality constant K_(x) may be selected by a user in a settings menu. In another exemplary embodiment, the value of proportionality constant K_(x) may be a function of the rate of change in the horizontal position of an uninterrupted finger contact on the PPC icon.

10) Alternative PPC icon designs and alternative vertical fine-adjustment icon designs:

We have shown several example PPC icon designs in FIG. 3J. There are other variations on the design of the PPC icon with respect to the size and shape of the icon and presence of transparent and/or semitransparent regions, and other features and aspects that may work equally well. For example, the horizontal extent of PPC icon can be less than or equal to the horizontal extent of the display. For example, the horizontal extent of PPC icon can be substantially equal to, approximately one-half of, or approximately one-fourth of the horizontal extent of the display. The value for Kx and the functional dependence of Kx on the time rate of change of finger position in the x direction can be set by the user to provide good usability for the particular horizontal extent of the PPC icon. Finally, the size and shape of the PPC icon can changed to suit the needs of a particular application or use case. The vertical extent of the PPC icon can be chosen similarly. For example, the vertical extent of the PPC icon can be less the vertical extent of the pointer. The vertical extent of the PPC icon can be substantially equal to the vertical extent of the pointer. Finally, the vertical extent of the PPC icon can be two to four or more times the vertical extent of the pointer.

We have shown two example vertical fine-adjustment icon designs in FIG. 8C and FIG. 8F. There are other variations on the design of the vertical fine-adjustment icon with respect to the size and shape of the icon and presence of transparent and/or semitransparent regions, and other features and aspects that may work equally well. In other embodiments the value of Ky may be made a function of the time rate of change in the vertical position of the finger contact.

The methods and UI of this disclosure may include the use of stylus gestures in addition to, or in lieu of finger gestures.

Settings Parameters I:

-   -   The methods and UI may include enabling the user to specify via         settings a number of parameters. These may include, but are not         limited to, the enabling the user to specify one or more of the         following:

Specify K_(x) where ΔP_(x)=K_(x)ΔF_(x), ΔP_(x) is the change in the pointer position in the x direction, ΔF_(x) is the change in the finger position on the PPC icon in the x direction, and K_(x) is a constant. This can be illustrated by the following three examples: 1) If K_(x)=0.25 and the user changes her finger position on the PPC icon in the x direction by a distance equal to the full width of the display, then the device will change the position of the pointer in the x direction by a distance equal to ¼^(th) the width of the display. 2) If K_(x)=1.0 and the user changes her finger position on the PPC icon in the x direction by a distance equal to the full width of the display, then the device will change the position of the pointer in the x direction by a distance equal to the width of the display. 3) If K_(x)=4.0 and the user changes her finger position on the PPC icon in the x direction by a distance equal to ¼^(th) the width of the display, then the device will change the position of the pointer in the x direction by a distance equal to the width of the display.

Specify K_(x) where ΔP_(x)=K_(x)ΔF_(x), ΔP_(x) is the change in the pointer position in the x direction, ΔF_(x) is the change in the finger position on the PPC icon in the x direction, and where K_(x) is a function of the time rate of change of the finger position on the PPC icon in the x direction. This can be written K_(x)=f(dΔF_(x)/dt). In one example embodiment this may include enabling the user to specify the dependence of K_(x) on the time rate of change of the finger position on the PPC icon in the x direction by enabling the user to set a “pointer speed” parameter over a range of values from “slow” to “fast”. In this example embodiment, with a “pointer speed” parameter set by the user at the “slow” end of the range, K_(x) may be approximately constant with a weak dependence on the time rate of change of finger position on the PPC icon in the x-direction. With a “pointer speed” parameter set by the user at the “fast” end of the range, K_(x) may have a strong dependence on the time rate of change of finger position on the PPC icon in the x-direction. With a “pointer speed” parameter set by the user at the mid-range position, then K_(x) may have a moderate dependence on the time rate of change of finger position on the PPC icon in the x direction. This can be illustrated by the following example. When the time rate of change of finger position on the PPC icon in the x direction is small, then the device may set K_(x)=0.25; when the time rate of change of finger position on the PPC icon in the x direction is large, then the device may set K_(x)=1.0.

Specify KF_(y) where ΔP_(y)=KF_(y)ΔFF_(y), ΔP_(y) is the change in the pointer position in the y direction, ΔFF_(y) is the change in the finger position on the vertical fine-adjustment icon in the y direction, and KF_(y) is a constant. This can be illustrated by the following two examples. 1) If a user changes her finger position on the PPC icon in the y direction by a distance equal 4 mm, then the device will change the position of the PPC icon and the position of the pointer in the y direction by a distance of 4 mm since ΔP_(y)=ΔPPC_(y)=K_(y)ΔF_(y) where K_(y)=1. 2) If KF_(y)=0.25 and the user changes her finger position on the vertical fine-adjustment icon in the y direction by a distance of 4 mm, then the device will change the position of the pointer in the y direction by a distance of 1 mm since ΔP_(y)=ΔPPC_(y)=KF_(y)ΔFF_(y) where KF_(y)=0.25.

Settings Parameters II:

The methods and UI may include enabling the user to specify via settings a number of parameters. These may include, but are not limited to, the enabling the user to specify one or more of the following:

The user may define a “secondary-click” finger gesture. For example the user may define a secondary click to be one the following finger gestures or a combination thereof: 1) a two-finger-tap finger gesture on the PPC icon, 2) a one-finger-tap finger gesture near the rightmost end of the PPC icon, 3) a one-finger-tap finger gesture near the leftmost end of the PPC icon. Example “secondary-click” finger gestures are illustrated in FIGS. 13C-13E. A secondary-click finger gesture is the analog to a mouse “right click” or touch-pad “right click” on a desktop or notebook computer. Other alternative secondary-click finger gestures may be chosen including those incorporating finger gestures on other icons on the device's touch-sensitive display.

The user may define the behavior of the select mode or drag mode. The user may specify select lock (sometimes called drag lock) to be off. In this mode with select lock off, the device would end the selection of content in response to detecting that the user has lifted his finger at the end of a tap-and-slide finger gesture on the PPC icon. The user may specify select lock (sometimes called drag lock) to be on. In this mode with select lock on, the device would not end the selection of content in response to detecting that the user has lifted his finger at the end of a tap-and-slide finger gesture on the PPC icon. The device would end the selection in response to detecting a tap finger gesture after detecting that the user has lifted his finger at the end of the tap-and-slide gesture on the PPC icon. This select lock/drag lock functionality enables a user to conveniently drag an object from one location on the display to another desired location. Here the user performs a tap-and-slide gesture on the PPC icon with the pointer positioned on an object that the user wishes to drag from one position to another. With select lock/drag lock turned on, the user may conveniently drag the object using one or more slide gestures and then end the drag with a one-finger-tap finger gesture on the PPC icon once the object has been moved to the desired position.

In one exemplary embodiment, the user may define alternative gestures for placing the cursor at the position of the pointer following a slide gesture for positioning the pointer. In one setting, this can be a slide gesture on the PPC icon to position the pointer followed by a tap gesture on the PPC icon to place the cursor at the pointer. In another setting, this can be a slide gesture on the PPC icon to position the pointer followed by a finger lift to place the cursor at the pointer. In one exemplary embodiment, the latter gesture alternative can be made active when lift-to-tap is set to “on”.

In another exemplary embodiment, the user may define alternative gestures for a select gesture at the position of the pointer following a slide gesture for positioning the pointer. In one setting, this can be a slide gesture on the PPC icon to position the pointer followed by a tap gesture on the PPC icon to select the item at the position of the pointer. In another setting, this can be a slide gesture on the PPC icon to position the pointer followed by a finger lift to select the item at the position of the pointer. In another exemplary embodiment, the latter gesture alternative can be made active when lift-to-tap is set to “on”.

Settings Parameters III:

The methods and UI may include enabling the user to specify via settings a number of parameters for providing enhanced accessibility for users. These may include, but are not limited to, the enabling the user to specify one or more of the following:

A user may change the size of the pointer from a standard size (about 12 points in height for example) to a larger size by setting a slider control or by other means to better suit the needs or preferences of the user.

A user may change the vertical extent of the PPC icon from a standard size (about 12 points in height for example) to a larger size by setting a slider control or by other means to better suit the needs or preferences of the user.

A user may change K_(x) as outlined above under Settings Parameters I to better serve the needs of the user for convenient and precise horizontal positioning of the pointer.

A user may change KF_(y) as outlined above under Settings Parameters I to better serve the needs of the user for convenient and precise vertical positioning of the pointer.

Enabling the user to define the use of alternative gestures or actions such as voice commands, hand gestures, gaze gestures in addition to, or in lieu of, a particular finger gesture.

Alternative Devices with Touch-Sensitive Displays:

Whereas we have focused this disclosure on methods and graphical user interfaces for pointing and editing on mobile computing devices with touch-sensitive displays such as smart phones and pad computers, these methods and graphical user interfaces may be used with other devices with touch-sensitive displays including, but not limited to, notebook computers with touch-sensitive displays, notebook/pad hybrid devices with touch-sensitive displays, public kiosks with touch-sensitive displays, and equipment and instruments touch-sensitive displays.

This Disclosure Also Includes, but is not Limited to, the Following:

This disclosure includes methods comprising a handheld computing device 100 with a touch-sensitive display implementing one or more of the methods selected from those described in reference to FIGS. 3-13 and those described in FIG. 14, FIG. 15, FIG. 16, FIG. 17, and FIG. 18.

This disclosure includes a handheld mobile computing device 100 comprising a touch screen display, one or more processors, memory; and one or more programs, wherein one or more programs are stored in memory and configured to be executed by the one or more processors, the one or more programs including instructions for implementing one or more of the methods selected from those described in reference to FIGS. 3-13 and those described in FIG. 14, FIG. 15, FIG. 16, FIG. 17, and FIG. 18.

This disclosure includes a computer readable storage medium storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a handheld mobile computing device 100 with a touch screen display, cause the device to implement one or more of the methods selected from those described in reference to FIGS. 3-13 and those described in FIG. 14, FIG. 15, FIG. 16, FIG. 17, and FIG. 18.

This disclosure includes graphical user interfaces on a computing device with a touch sensitive display, memory, and one or more processors to execute one or more programs stored in memory, the graphical user interfaces comprising the one or more graphical users interfaces selected from those described in reference to FIGS. 3-13 and those described in reference to FIG. 14, FIG. 15, FIG. 16, FIG. 17, and FIG. 18.

Throughout this disclosure we have referred to pointer 310. We have also referred to cursor 508. Finally, we have referred to selected text, denoted by some marker such a highlighting, showing the start and end of the selection within a body of text. One selection example is selection 408 described in reference to FIG. 4D. To avoid confusion in this disclosure, let's describe again each of these items in the context of existing devices and existing graphical user interfaces.

The cursor is sometimes called an insertion mark. In this disclosure the cursor is displayed as a vertical bar. The user may position the cursor to mark the location at which text entry can begin within an editable content displayed on a display screen. In the case of a new document with no text, the cursor is displayed by default at the first position in the document where text may be entered. Since the cursor marks a text entry location, a cursor is displayed within editable content and no cursor is displayed within read-only content. The cursor is familiar to any user of a word processing application.

A text selection is also a type of mark. The user may select the location of the start of a text selection and the location of the end of that text selection. The mark denotes the portion of text that has been selected by the user. Highlighting or other means may be used identify the selected text. Since text may be selected for example for cut, copy, or paste operations within editable content, and for copy operations within read-only content, selected text may be displayed within both editable and read-only content. The selection of text is again familiar to any user of a word processing application.

A pointer is familiar to any user of an application such as a word processing application designed for use with a desktop or notebook computer. The pointer is displayed on the display screen along with any content. The user may employ a mouse device or touch-pad device to change the position of the pointer on a display screen. In one example, the user may position the pointer to a location within a displayed text document. The user may then click or tap the mouse or touch pad to place the cursor at the location of the pointer. In another familiar example, the user may position the pointer to a location within a text document at the start of a selection, hold the mouse button down while sliding the mouse to select a portion of the text content, and then release the mouse button to end the selection.

A marker such as a cursor or a selection is associated with content and thereby moves with the content if the content page is scrolled. The position of the pointer does not move with the content. The movement of the pointer is independent of movement of the content. Moving the content by page scrolling or other means does not move the pointer.

The pointer may be used to position a marker like a cursor or define the starting and ending location for a selection. The pointer may be used to drag an object on the display screen from one location to another. The pointer may be used for example to resize an image or object by placing the pointer on a drag handle at the edge or corner of the image and then moving the pointer to resize image or object. The pointer may be used to select an icon displayed on the display screen to select an action like copy, print, or save. The pointer is not associated with content like a cursor, a selection, or a drag handle.

Desktop and notebook computers employ a graphical-user-interface designed for use with a device such as a mouse or touch pad for controlling the position of a pointer on the display screen. Mobile computing devices with a touch-sensitive displays employ a graphical user interface designed for use with the user's finger as the pointer. Whereas the graphical user interfaces for these devices do include on-screen markers such as the cursor, selection marks, and drag handles for moving a cursor, resizing images, shapes, and selections, the graphical user interfaces of these devices do not employ a pointer. The pointer for these devices with touch sensitive displays is the user's finger. This UI design has a number of deficiencies as previously described in the background section.
